In medical applications, there is a trend towards ever more precise and refined, and therefore expensive and complex, diagnostics, including personalized medicine. At the same time, there is an opposing trend towards more frequent, simpler and cheaper diagnostic sampling supported by portable or wearable sensors, which tends to be used to determine progression and does not always have to be extremely accurate, supported by intelligent systems based on closed feedback systems. One example is the “hospital at home”, especially for patients with chronic illnesses or when hospital stays or visits are complicated to organize.
The trend towards ambulant or hospital external medicine is justified by lower costs, improved and simplified long-term monitoring and the exclusion of examination bias. Modern sensor concepts support this development.
